Sofia is home to a remarkable collection of historical buildings that reflect its rich and diverse past. The **Alexander Nevsky Cathedral**, with its impressive golden domes and Neo-Byzantine architecture, is one of the city’s most iconic landmarks. It stands as a testament to Bulgaria’s religious and cultural history.

Not far from there, you’ll find the **St. Sofia Church**, after which the city is named. This 6th-century Byzantine church is a beautiful example of early Christian architecture. Nearby, the **Rotunda of St. George**, a 4th-century Roman structure, offers visitors a glimpse into Sofia’s Roman era, with its ancient frescoes still visible inside.

The **National Palace of Culture**, an imposing structure built in the 1980s, blends socialist realism with modern design, and is a symbol of Bulgaria’s post-communist era. For a touch of royal history, visit the **Royal Palace** (now home to the National Art Gallery), a stunning building that once served as the residence of Bulgaria’s royal family.

Sofia also has several Ottoman-era buildings, such as the **Banya Bashi Mosque**, which was built in the 16th century and stands as a reminder of the city’s time under Ottoman rule. These historical buildings, spanning various periods and styles, create a fascinating architectural landscape that tells the story of Sofia’s vibrant history.
